Any puma7 firmware?

[doctor]

if anyone is planning to purchase a hitron 4582 unit for testing , just to let you know you will not be able to inject your working certs from older units from puma6 and down into this unit because it uses a total of 9. 4 are docsis 3.1 . But on the bright side you can take working certs out of a puma7 and use it on older modems ,but why would you .
root_pub_key
mfg_cert
mfg_key_pub
cm_cert
cm_key_prv
D3_1_cm_device_prv_key
D3_1_root_ca_cert
D3_1_cm_device_cert
D3_1_device_ca_cert

This is an interesting change. Is this because of DOCSIS 3.1 or because of the modem itself?

Yes, it is a change in the DOCSIS 3.1 standard.

DOCSIS 3.1 certificates have a different root and different set of MFG certificates.
This is the only difference - functionally they are identical, just a different root/MFG.

This also means it is not possible to "convert" D3.0 certs to D3.1, as they are literally just signed differently.

However, you can use D3.0 certificates on D3.1 modems - you just have to disable D3.1 mode.
You will not be able to use OFDM/OFDMA channels unless you have a valid D3.1 certificate, but your 32x8 D3.0 channels will work.

Interesting. How do you disable d3.1 mode ? also I just tried using a config.cm from a d3.1 modem in bitware and the speed was all over the place. The file is 7kb one kb larger than a d3 modem. I was able to use it in forceware but the max the modem can handle is 300mbps now that i have the sb6190 i would like to push it to the limit.
